Water Repellents & Sealers.
Deep-acting protection for stone, concrete, brick and fabric. Our water repellents penetrate deep into the material, make it water-repellent and protect against moisture, frost and soiling, without changing the natural appearance.
What is a water repellent?
A water repellent is a protective treatment that penetrates deep into porous materials and makes them water-repellent from within. Unlike a film-forming surface sealer, it forms no visible layer on the surface.
The result: water beads off, dirt does not adhere, yet the material stays almost fully vapour-permeable. Moisture from inside can still escape, the component breathes.
Water repellent
- Penetrates deep (up to 15 mm)
- Vapour-permeable, the material breathes
- Invisible once dry
- For absorbent, porous materials
Surface sealer
- Forms a film on the surface
- Closes the pores
- Often visible or slightly glossy
- For smooth, dense materials
Water repellents for every substrate.

Water repellent or surface sealer?
Two systems, one protective idea. The key differences at a glance.
Six answers on water repellents.
Q01 Water repellent or surface sealer, which one is right for me? +
Rule of thumb: absorbent, porous materials (brick, concrete, natural stone, fabric) get a penetrating water repellent. Smooth, dense surfaces (glass, ceramic, paint) get a film-forming surface sealer. A penetrating repellent has no effect on glass, and a film-forming sealer forms no meaningful layer on brick.
Q02 How long does a water repellent last? +
5 to 15 years, depending on material, weather exposure and load intensity. South and west facades face more UV, industrial floors more mechanical stress, so expect 5 to 8 years there.
Q03 Does the water repellent change the appearance? +
No. Once dry, the water repellent is completely invisible. Neither color, gloss nor texture changes.
Q04 Are the products suitable for private customers? +
Yes. All water repellents are designed as DIY products and can be applied with a brush, roller or pump sprayer. On request we advise you by phone before purchase.
Q05 Can I get a sample before buying? +
Yes, for all water repellents we supply free samples (plus 7.50 EUR shipping). The sample quantity is usually enough for 1 sq m. On request we advise you by phone in parallel.
